Hi,
I decided to share some dependencies of certain sccm roles, and their related services with all, which might have caused headaches for some.
Please add basic troubleshooting steps for common issues if you find some.
If wsus does not start up, please ensure the following:
Is your sql server service running?(This is only if your WSUS database is hosted on the sccm sql database)
If you have difficulties accessing the sccm management console, restart the MSSQL service in services.msc
If pxe boot does not work properly, restart the wds role.
If wds does not start up, restart the "Server" service, and retry.
Note to always set your WDS service to "Delayed start", as to give time for your depaendant services to start up first.
As a rule of thumb, when communication issues are experienced, it should be the first step to restart the mssql service.
If boot images, etc are inaccessible, ensure that WAIK is installed.
When you experience update issues, after a windows update has come through, remember that sometimes hotfixes are available for the WSUS server instance to restore communication.
